Abstract

The invention discloses a breast pump. The breast pump comprises a main machine and a three-way assembly, wherein an inserting groove of the main machine is connected with an inserting part of the three-way assembly in an inserted mode; the three-way assembly comprises a suction cylinder shell and a suction piston installed in an inner cavity of the suction cylinder shell; the suction piston is used for dividing the inner cavity of the suction cylinder shell into an internal cavity communicating with a milk suction channel and a suction cavity communicating with a suction pump of the main machine; an air vent communicating with the suction cavity is formed in the suction cylinder shell; a suction opening communicating with the suction pump is formed in the inserting groove of the main machine; and a horn-shaped sealing ring is arranged at the suction opening, so that after the three-way assembly is inserted in place, the horn-shaped sealing ring can cover the air vent and is compressedto be tightly attached to the outer surface of the suction cylinder shell. The breast pump can effectively solve the problem of poor assembling effect of the three-way assembly and the main machine of an existing breast pump.

Description

technical field [0001] The invention relates to the technical field of maternal and infant products, and more specifically, relates to a breast pump. Background technique [0002] Breast pumps generally mainly include a main unit and a three-way assembly. For some breast pumps, a feeding bottle assembly is also provided correspondingly to connect with the milk outlet of the three-way assembly. The three-way assembly is mainly a three-way interface, one of which is used for gas inlet and outlet, one of which is provided with a breast shield, and one of which is a milk outlet for connecting with the feeding bottle assembly. [0003] The current wearable breast pump can better solve the problem of inconvenient carrying of the breast pump. The wearable breast pump is directly stuffed into the bra to pump milk, no need to hold it, which can free your hands. However, the current wearable breast pumps are prone to air leakage due to structural design problems, resulting in no suc...
